工業(ye)用(yong)電導(dao)率(lv)探(tan)頭是一(yi)種用(yong)于測(ce)量(liang)液(ye)體(ti)電導(dao)率(lv)的傳感器，它基(ji)于電導(dao)性的原理，通過測(ce)量(liang)液(ye)體(ti)中(zhong)離子(zi)與(yu)電流之間的關系來(lai)推測(ce)液(ye)體(ti)中(zhong)的離子(zi)濃度。

電(dian)(dian)(dian)(dian)導(dao)率(lv)(lv)(lv)(lv)探頭(tou)是測量(liang)水質電(dian)(dian)(dian)(dian)導(dao)率(lv)(lv)(lv)(lv)值參數(shu)的(de)(de)電(dian)(dian)(dian)(dian)導(dao)率(lv)(lv)(lv)(lv)儀的(de)(de)組成部分或配件。電(dian)(dian)(dian)(dian)導(dao)率(lv)(lv)(lv)(lv)，物理學概念，也可以稱為導(dao)電(dian)(dian)(dian)(dian)率(lv)(lv)(lv)(lv)。在介質中(zhong)該量(liang)與電(dian)(dian)(dian)(dian)場強度E之積等于傳導(dao)電(dian)(dian)(dian)(dian)流密度J。對于各向(xiang)同性介質，電(dian)(dian)(dian)(dian)導(dao)率(lv)(lv)(lv)(lv)是標量(liang);對于各向(xiang)異性介質，電(dian)(dian)(dian)(dian)導(dao)率(lv)(lv)(lv)(lv)是張(zhang)量(liang)。生態學中(zhong)，電(dian)(dian)(dian)(dian)導(dao)率(lv)(lv)(lv)(lv)是以數(shu)字表示(shi)的(de)(de)溶液傳導(dao)電(dian)(dian)(dian)(dian)流的(de)(de)能力。單位以西門子每米(S/m)表示(shi)。
